3Racing TAMIYA M05 Graphite Rear Pin Stiffener M05-07/WO - Replacement Part  [M05-07/WO]

Precision rear suspension pin stiffener for TAMIYA M05

This graphite rear suspension pin stiffener is an aftermarket component for the TAMIYA M05 chassis, designed to reduce flex at the rear pin joint and produce a more predictable rear-end response while adjusting setup. The unit installs as a direct replacement without modifying chassis geometry.

Fitting is straightforward for experienced hobbyists: remove the existing rear pin or plate, slot the stiffener into the factory mounting points and refit the original fasteners. No specialised tooling is necessary and the part works with standard M05 rear suspension items.

During tuning the stiffener helps to firm the rear and steady minor steering inputs, pairing effectively with spring, damper and toe adjustments. Being graphite, the change is in mechanical stiffness rather than any electronic or servo characteristic.
